AUTOMOBILE JACK HANDLE.

Application filed March 23, 1925.

1 all whom it may concern:

Be it known that I, Josnrrr Anniuso, a subject of the King of Italy, residing at Milford, county of Worcester, and State of .ssachusetts, have invented certain new and useful Improvements in an Automobile Jack Handle, of which the following is a specification.

This invention relates to improvements in automobile jack handles.

The primary object of this invention is the provision of an extensible handle construction adapted for use with vehicle acks, embodying a novel construction by which a relatively long jack handle may be provided in sections which may be compactly collapsed. I

A further and important object of this invention is the provision of an extensible handle construction for automobile jacks, of a type particularly well adapted to be used in connection with my improved vehicle jack set forth in my copending application, Serial No. 17,828, filed March 23, 1925 Other objects and advantages of this invention will be apparent during the course of the following detailed description.

In the accompanying drawing, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views,

Figure 11 is a side elevation, partly in section, showing the improved construction of the extensible handle as used in connection with an automobile jack.

Figure 2 is a side elevation showingthe improved automobile jack extension handle in a collapsed position.

Figure 3 is a view illustrating the collapsed position of the extension handle; this view being taken at right 'angles-to the view illustrated inFigure 2.

Figure l is a fragmentary view showing details at a hinge joint in the improved handle, with the sections thereof extended.

Figures '5, 6, and 7 are cross sectional views taken substantiallyfon their respec tive lines inFigures 2, t and '1 of the drawg .H

is the drawing, wherein for the purpose ofillustratijon is shownonly a preferred.

e b dimen of the i prered"handle et ucf ture, the letter A: may generally designate a Serial No. 17,829.

jack structure of any approved character, with which the improved extension handle B may be used to operate the same.

The jack A in the preferred instance is of the construction set forth in my co-pending application above referred to, and includes the housing 10 within which the elevating screw 11 is positioned. The operating mechanism for the jack'screw structure 11 comprises an operating gear 12, with which a pinion 13 meshes. The pinion 13 is rotatably positioned within the housing 10 upon a pinion shaft 14, which at its inner end has a step bearing 15 in the housing 10, and at its outer end has a bearing in the passa eway of a sleeve portion 16 of the housing 10. The pinion shaft at its outer end projects from the sleeve 16, and has a socket sleeve 17 keyed thereto as by a pin 18; the socket sleeve 17 providing anoutwardly facing and upwardly inclining polygonal opening 19 therein adapted to receive an end of the extension handle B, as is illustrated in Figure 1 of the drawing.

Referring to the construction of the improved extension handle B, the same preferably comprises a pair of relatively long bar sections and 26, which are preferably of the same size, and square in cross section from end to end. 'These sections 25 and 26 may be distinguished from each other by respectively calling the same inner and outer sections. and they are pivotally connected for extension or collapsing by means of a novel strong structure 28. On the outer en; of the outer section 25 it is preferred to collapsibly position a novel type of hand engaging structure 29 to be subsequently described;

Referring to the joint structure 28, the same preferably comprises a substantially U-shaped spring steel punching or connecting piece 30, and steel puncliings 31 and 32 connected respectively with the handle extension sections '25 and 26.

.s t 5 at its outer end is Pr ferly p de .With the shim 0 nuns 1 ;;wh 0h a 1 We .ll s 'at d jlnFlsure 'th dra i g prise a ushere bo y which includes a lower wall 3S and side. walls Bet in right angled relationto the wall 38,"'and in parallel"relation to each other. The out r end of the 569 1911 1 nugly fit within'the'p'ocket of this shin: 31', "so that edges are inwarc the upper edges of the walls 34 he flush with the adjacent surface or side of the handle section and preferably so that the for ward end or go of the shim 31 lies flush with the outer end edge of the section 25, as is illustrated'in Figure 1. This punching 31 is fixedly connected in the position mentioned upon the handle section 25 by means of a strong rivet'or pin 38, which transvcrsely extends through the section 25 and through the side walls 3%, and also through the side vvalls of the steel spring punching or connecting piece 30 to be subsequently escribed;

At the inner end of the handle section 26 is rigidly positioned the steel punching hinge piece 32, which is of son'iewhat novel ii'orniation, being U-shaped in cross section, and of l.shaped outline, as to length. It 0 niprises. the bottom wall 89, is illus trated in Figure (3, with the right angled spaced parallel side walls d0 connected therewith and providing the pocket 41 therein into which the inner end of the handle section 26 is positioned and atlixed therein by means of a transverse rivet or pin connected through the section 26 and the side walls 40. Atthe forward end the side Walls 40 of the piece 32 are upivardly extended from the adjacent edges of the rear portions of the side walls it), these iu'nvardly extending portions 48 of the side walls l0 being spaced and in parallel relation, is illustrated in Figure 6 of the drawing. The inner end of the bottom wall 39 arcuated, as at 49, to permit the pivotal action of the piece within the connecting piece 30.

The section connecting piece 30 is preferably a sprin steel. punching, being very strong, and or lJ-shaped cross section, comprising the bottom wall 52, with the upstanding spaced parallel walls 53 in right angled relation therewith. The pocket provided by this connecting piece 30 receives the shim 31 and the outer end of the section 25 therein, and is connected thereto by means of the rivet or pin 38 above i'nen tioned. In therear portion of the connecting piece 30 the outer section 26 is pivotally connected by means of a pin or rivet 55, which extends thru the side walls of the piece 30, and through the upwardly extending portions 48 of the side walls of the piece This pin acts as a pivot for the sec tion 26 upon the connecting piece 30, and the said pivot pin 55 provides a pivot axis which is positioned laterally of the meat of the sections 25 and 26, when they are in ex tended position The side walls 53 are relatively deep, and brace the pieces 3i and 32 throughout m their heights. ihe top ed 58 of the portions 48 are belovr the top edges 55) of the side walls 53 of the connecting piece 30, and said side walls above the ly ing purposes.

crimped, to provide catch ears or portions which overlie the edges 58 at the outer end of the piece 30, with a spring clamping action to maintain the sections 25 and 26 in alignment. In this position the bottom wall 39 is of course placed in engagement with the bottom wall. 52, so that the handle sections 25 and 26 are held in alignment against moving in any direction.

The sections and 26 may be collapsed into parallel relation, and to ell'ect this it is merely necessary to overcome the spring action of the side walls 53, flexing the same by forcing the catch portions or ears 60 apart, so that the handle sections may be moved into collapsed position. This flexing of the side Walls 53 of the connecting piece 30 is illustrated in Figure 3 of the drawing, and binds the ears or catch portions 60 against the side walls ll) of the outer section attached piece 32, with suflicient frictional engagement to hold the handle sections in a collapsed condition. As the attaching pin i t is provided with the heads in in outwardly bulging relation at the sides thereof, it is preferred that the upwardly extending side walls 53 of the connecting piece 30 above the rivet 3 be provided with lateral bulge a clrets 64 for the accommodation of said heads i l and as is illustrated in Figure of the drawing. This permits a compact parallel collapsing of the handle sections.

Referring to the hand engaging structure 29, the same preferably comprises a pair of oppositely disposed hand bars and 71, pivoted as by pins or rivets 72 upon a spring steel punching piece 74. The U- shaped connecting piece 74: preferably comprises a bottom wall 75, and the spaced parallel side walls 76. The outermost end of the outer section 26 is rigidly fastened in the steel punching piece 74 between the side Walls 76, by means of a rivet or pin 78; the handle section 26 entering the pocket between the walls 76 in a right angled relation to the bottom wall 75, and extends through a square opening in said wall to -rigidly position the length of the steel punching piece 74 crosswise at the end of the handle section 26. The hand bars 70 and T1 are pivoted at opposite sides of the handle section 26, and it is preferred that struck, at 80, to brace the hand bars 70 and 71 thereagainst when they are in their 8X- tended aligning relation for hand engag- At each side of the .handle section 2 the side walls 76 are inwardly crimped to provide the catch portions'or cars 62, similar to the cat-ch portions 60. above mentioned, and for the purpose of springing into position over the adjacent i outer surfaces of the handbarsZO and 71,

s th ira at endee-in a he d that Lit) ' scribed ial positions when the hand 71 are collapsed against the "-6, and again cooperating in hand bars in such collapsed s is illustrated in Figures 2 and 5 of the drawings.

It is to be particularly noted that in operation the inner end of the inner section is slipped into the square sociret opening 19, and i n-ca position the handle section 26 and collapsed hand bars and 71 may be collapsed upon the secion 25, and in such collapsed position the section 26 and the connected hand bars TO and 71 will not abut the socket 1'7, since the inserting end or the section projects beyond the end wall 5 of tie hand connecting piece 7%,

illustrated in Figures 2 and?) of the drawing. it is to be particularly noted that he hand bars collapse in a plane with the ection 26, which is at right angles to the Jlane defined by the collapsed handle secons and 26, thus providing a very compact collapsing arrangement.

From the foregoing description of this invention it is apparent that a novel type of extension handle has been provided, which admirably serves the purpose of providing a acl; handle, in that the same when extended is very strong, and yet may be collapsed into very compact position, which is very essential in connection with an automobile jack where the jack handle has to be stored within limited space.

Various changes in the shape, size, and arrangement of parts may be made to the form of the invention here-in shown and described, without departing from the spirit of the invention or the scope of the claims.
